Here are some simple examples of policies:
Avoid writing in CAPITAL LETTERS
Find PDFs newer than September 2018
Write your name in a specific way (“University of X”, never “X University”)
Avoid gender-specific professions (“firefighter” instead of “fireman”)
Add a trademark symbol next to all uses of your brand names
When linking to a 3rd party, include “external link” in the text for the link
More generally, policies can identify parts of webpages or PDF documents based on rules that you define.
